To succeed in Detroit, it’s not enough for polypropylene-based TPO elastomers to be low-cost, lightweight, easily processable, and recyclable. They also have to look good for the life of the vehicle.
New systems to process mixed plastic waste and to upgrade it with fiberglass or wood flour were prominent at last June’s show in Chicago. Single-shaft rotary grinders made a strong showing as newer alternatives to conventional granulators and shredders.
Since the advent of metallocene-catalyzed plastomer and LLDPE film resins, improving processability while retaining their inherently high physical and optical properties has been an industry target.
Improved designs of high- and low-pressure metering systems will be displayed at NPE 2000. Look also for new CO2 blending systems and an upgraded pentane mixing system.
From auto parts to barrier packaging, the race is on to commercialize nano-clay thermoplastic composites. Just a pinch of these infinitesimally small particles can dramatically raise mechanical, thermal, barrier, and flame-retardant properties.
If you're looking for a film resin with the outstanding heat-sealability of metallocene plastomers but with higher stiffness for easier converting, you may want to try the new Mxsten CV family of linear hexene copolymers resins from Eastman Chemical Co., Kingsport, Tenn.
